[Application of quantum dot to life science].

As an eminent representation of nanotechnology, quantum dot (semiconductor nanocrystal) has caught great interests of scientists in physics, chemistry, material science, and biology extensively. Although its application to life science has just been explored, valuable progresses have been achieved in both biomacromolecule labeling and coding recently. The progress in quantum dot synthesis, its spectroscopic and photoelectronic properties, and its potential application to life science are reviewed.
